Description

Glasses with audio speakers in the temple

The present invention generally relates to audio glasses and methods of their use.

Traditionally, earphones have been used to present sound to individuals when they wish to have privacy or do not wish to interfere with others. Examples of conventional earphone devices include a headphone on the head with an ear cup speaker (for example, Beats® for Dr. Dre's headphones); ear buds type earphones (For example, Apple iPod® headsets and Bluetooth® headsets; bone-conducting speakers (for example, Google Glass). Another known way of achieving the desired privacy or peace and quiet that others desire is formed by using a directional multi-speaker beam. Additionally, well-known but not known devices in the prior art for presenting sound to a hearing impaired individual are hearing aids. An example of this is the Open Head-Behind-the-Ear (BTE) device of the receiver in the Receiver-In-The-Aid (RITA). The hearing aid typically includes a transparent "hook" that acts as a sound-conducting hose for conveying the audio (also called a receiver in a telephone application) sound to the inner ear of the user and acting as a mechanical support. The user can wear the hearing aid, and the speaker is stored in the back of the ear of the hearing aid body. However, all of the aforementioned techniques have drawbacks, in other words, they are bulky, cumbersome, unreliable, or unmistakable.

Therefore, the present technology requires an earphone to overcome or minimize the above cited problem.

The present invention is generally related to audio glasses and methods of their use.

In one embodiment, the audio glasses of the present invention comprise a front frame and at least one temple or side frame member, the at least one temple or side frame member being fixed to the front frame for fastening the user's ear . The at least one frame member has a speaker that is oriented such that an audio cassette of the speaker faces downwardly away from the angle of the front frame and the at least one frame member to substantially sound along a vertical plane Push down into the user's ear.

In a particular embodiment of the invention, the eyewear device further includes an array of microphones coupled to at least one of the front frame and at least one of the frame members. The microphone array includes at least one first microphone and a second microphone. The first microphone is located at a temple region between the top corner edge of the lens opening defined by the front frame and having an inner edge and the at least one side frame member. The second microphone is located at the inner edge of the lens opening. This embodiment of the eyewear device further includes a first audio channel output and a second audio channel output from the first and second microphones, respectively.

In another special embodiment of the present invention, the eyeglass device additionally includes a beam former electrically coupled to the first microphone and the second microphone for receiving at least the first audio channel and the second The audio channel also outputs a main channel and one or more reference channels. An audio activity detector is electronically coupled to the beamformer for receiving the primary channel and the reference channels and outputting the desired audio active channel. An adaptive noise canceller electrically coupled to the beamformer and the audio activity detector for receiving the primary pass Channels, the reference channels, and the desired audio active channel and output an adaptive noise cancellation channel. A noise reducer is electronically coupled to the audio activity detector and the adaptive noise canceller for receiving the desired audio active channel and the adaptive noise cancellation channel and outputting a desired voice channel.

Yet another embodiment of the present invention is a method of listening to audio, comprising the steps of: providing an audio eyeglass having a front frame and at least one side frame member, the at least one frame member being secured to the front a frame for fastening a user's ear, the at least one frame member has a speaker therein, and the speaker is oriented such that an audio cymbal of the speaker faces downward from an angle away from the at least one frame member for The sound is generally directed back and forth into the user's ear along the vertical frame.

In one embodiment of the method, a microphone array is coupled to the glasses, wherein the microphone array includes at least a first microphone and a second microphone. The first microphone is arranged to couple to the spectacles above the temple area, the position of the temple area being approximately between the top corner edge of the lens opening defined by the front frame and a support frame. The second microphone is coupled to the spectacle frame adjacent the inner edge of the lens opening. The first channel output and the second channel output are respectively provided by the first microphone and the second microphone.

In still another embodiment of the method, the method further comprises the steps of: forming a beam at a beamformer, the beamformer receiving at least the first audio channel and the second audio channel and outputting a master Channel and one or more reference channels. The audio activity is detected by an audio activity detector, wherein the audio activity detector receives the main channel and the reference channels and outputs a desired audio active channel. The noise is adaptively eliminated at an adaptive noise canceller that receives the main channel, the reference channels, And the desired audio active channel and outputting an adaptive noise cancellation channel. The noise is then reduced at a noise reducer that receives the desired audio active channel and the adaptive noise cancellation channel and outputs a desired voice channel.

The invention has many advantages. For example, the glasses of the present invention are relatively compact, non-obtrusive, and durable. Further, the apparatus and method of the present invention can be integrated with a noise canceling apparatus and method, which can also be a device of the glasses themselves, as appropriate. In one embodiment, the noise cancellation device (which includes a plurality of microphones, electrical circuitry, and software) can be integrated with the glasses worn by the user and, as the case may be, integrated on the circuit board of the glasses. In another embodiment, a microphone mounted on the circuit board of the glasses can be integrated with the speakers and circuitry (eg, a computer, receiver, or transmitter) to process the receipt from an external source or the The signal of the microphone, or the processing and transmission of signals from the microphone, and the selective transmission of the signals (whether processed or unprocessed) to the user of the glasses via a speaker embedded in the glasses. For example, human-computer interaction is becoming more and more popular through the use of voice recognition user interfaces. To facilitate this human-computer interaction, accurate speech recognition is very useful. It is also useful to be able to present information to a user via a spoken language, for example by reading a text to a user. Such machine output presents a hands-free action that helps the user to become more and more popular. The user does not have to hold the speaker or the device in the correct position, nor do they need to have electronic devices behind their ears or earplugs that would block their ears. In addition, there are no wires that are easily damaged, and the user does not have to endure the skin contact or pressure associated with the bone conduction speaker.

The same elements are denoted by the same elements throughout the various drawings, and the same reference numerals are used in the various embodiments of the invention. The drawings are not necessarily to scale, the

The present invention generally relates to audio glasses and methods of use thereof.

In one of the embodiments of the invention illustrated in Figures 1A through 1C, the audio glasses 10 include a front frame 12. Speakers (not shown) are included in the side frame members 14, 16. The speakers are configured such that the sounds of the speakers face downwardly at an angle away from the side frame members 14, 16 to generally direct the sound back into the user's ears along a vertical plane. 1B and 1C are alternative diagrams of the audio glasses of FIG. 1A.

In a particular embodiment of the invention, for example, as shown in FIG. 2, the side frame member 14 includes a thick front portion 24 that includes a speaker 18 and a thin rear portion 26 that extends rearwardly from the thick front portion 24 for use. To buckle the user's ear. The speaker 18 can be positioned within a cavity 20 formed in the at least one side frame member 14. As seen in Figure 3, the speaker 18 can be positioned at a downwardly facing down-converting surface 28 that narrows the thick front portion 24 into a thin rear portion along an upwardly extending upward angle 30. 26, and bend the audio cymbal 22 of the speaker 18 downward and backward. Referring back to Figure 2, the speaker 18 is positioned in the speaker plane 34, which is perpendicular to the sound direction axis 36 of the audio cassette 22, which is bent downward relative to the horizontal or longitudinal plane of the at least one side frame member 14. At least about 20 degrees or more (preferably, about 20 to 70 degrees) and is represented by angle 30. Referring back to FIG. 2, the speaker 18 is inlaid on the inner side 42 of the down conversion surface 28 using a sealing arrangement 48. The down conversion surface 28 defines a plurality of audio openings 46 for allowing sound from the speaker 18 to pass, such as As shown in FIG. 4, this figure is an exploded view of the left side frame 14. As shown in this figure, the seal arrangement 48 seals the speaker 18 and the printed circuit board 50 between the mask 52 and the audio opening 46 using the spacer 54 and the viscous spacer 56. The mask 52 is made of a suitable material, for example, a material known in the art, for example, which comprises rubber or anthrone. Gasket 54 and viscous gasket 56 are also made of a suitable material, such as materials known in the art. The compartment cover 58 is stacked over the sealing arrangement 48 and secured to the remainder of the left side frame 14 by screws.

In some embodiments, the left frame member 14 and the right frame member 16 are secured to opposite sides of the front frame 12. Each of the side frame members 14, 16 has an individual speaker for providing sound to both ears of the user. At least one of the right side frame member 16 and the left side frame member 14 and the front frame 12 may contain electronic components, a microphone (not shown), and a battery (not shown). The electrical signals from the speakers and the microphones are connected to a cellular phone (not shown). At least one of the electronic components and software in at least one of the glasses 10 and the cellular phone can automatically adjust the volume of the speaker based on environmental noise measured by the microphone.

In another embodiment, shown in Figures 5 and 6, a sound hose 60 is attached to at least one of the side frame members 14, 16 for audible sound from the side frame members 14, 16. The speaker (not shown) is guided into the user's ear. The sound hose 60 is inlaid into at least one side frame member 62 and defines an internal delivery opening 64 for receiving sound from the speaker and defines an external opening facing the user's ear for directing sound from the speaker to the user's ear Or directed to the ear canal.

In another embodiment, shown in Figure 7, the sound deflecting surface 66 extends from the outer surface of the at least one side frame member 62 and extends over a portion of the user's ear. The sound is delivered from a speaker (not shown) to the user's ear while also allowing ambient sound to be heard. In one embodiment, the sound conveying members (whether the sound hose or the sound deflecting surface) are removably attached by magnetic or mechanical attachment fittings and can be attached to Both the right frame part and the left frame part are directed to direct the sound to both ears.

The present invention can also provide a method of listening to an audio signal. Referring to Figures 1 to 4, there is provided an audio glasses 10 having a front frame 12 and at least one side frame member 14, 16 which is at least one side frame member 14, 16 is secured to the front frame 12 for fastening the user's ear. For example, the speaker 18 is oriented such that the audio cassette 22 of the speaker 18 faces rearwardly at an angle 30 away from the at least one side frame member 14 to generally direct the sound back and forth along a vertical plane. Among the ears.

Figure 8 is a schematic illustration of another exemplary embodiment of the eyewear 802 of the present invention having two embedded microphones in addition to the speaker and side frame components discussed above. The glasses 802 have two microphones 804 and 806, the first microphone 804 is arranged in the middle of the frame of the glasses 802, and the second microphone 806 is arranged on the side of the frame of the glasses 802. Microphones 804 and 806 can be pressure gradient microphone elements, bidirectional or unidirectional. Each of the microphones 804 and 806 is an assembly that includes a microphone (not shown) in a rubber cartridge, as further described below with reference to Figures 10A and 10B. The rubber long barrel provides a sound cymbal on the front side and the back side of the microphone having the sound tube. The two microphones 804 and 806 and their individual barrels can be identical. The microphone elements 804 and 806 can be hermetically sealed (for example, a hermetic seal) inside the rubber barrels. The sound conduits are filled with windshield material. The tethers are sealed by a layer of woven fibers. The lower sounds and the upper sounds are sealed by a waterproof film. Some of these The microphone can be constructed in the structure of the spectacle frame. Each microphone has a top hole and a bottom hole, which are sound hum. In one embodiment, the two microphones 804 and 806 (which can be pressure gradient microphone elements) can each be replaced with two omnidirectional microphones.

A schematic 950 of an exemplary embodiment of a pair of eyeglasses 952 having three embedded microphones is shown in FIG. Each of the pressure gradient microphone elements can be replaced by two omnidirectional microphones positioned at each of the sound cymbals, resulting in a total of four microphones. Signals from such dual omnidirectional microphones can be processed by the electronic or digital beamforming circuitry described above to produce a pressure gradient beam pattern. This pressure gradient beam pattern replaces the equivalent pressure gradient microphone.

In an embodiment of the invention, if a pressure gradient microphone is used, each of the microphones will be inside a rubber tube that extends the front and back sides of the microphone with the sound tube. At the end of the rubber tube, the new sound cymbal will align with the opening in the hose where the depleted space is filled with the windshield material. If two omnidirectional microphones are used instead of a pressure gradient microphone, then the sound of each microphone is aligned with the opening.

In one embodiment, a long speaker dual microphone binaural earphone would appear to be a conventional close-talk speaker microphone; however, it is a large speaker with two parallel microphones. The microphone at the end of the speaker is placed in front of the user's mouth. The dual-microphone design of the close-talking speaker is designed for military, aerospace, and industrial heavy-duty applications and has an unprecedented level of noise cancellation. For example, one of the main microphones will be positioned directly in front of the mouth. A second microphone will be positioned on the side of the mouth. The two microphones will have identical housings. The two microphones can be placed in parallel and perpendicular to the speaker. Every microphone There are front opening and back opening. The DSP circuitry can be located in a housing between the two microphones.

The microphone is stored in a rubber or tantalum holder (for example, a rubber long barrel), and if necessary, an air duct extends to the sound cymbals. The housing holds the microphone in an airtight container and provides an impact absorbing effect. The front and back of the microphones are covered by a windshield layer, which is made of a plurality of woven fiber layers or windshield foam materials for reducing wind noise. The delivery holes in the plastic housing of the microphone are covered by a waterproof film material or a special waterproof coating.

In another embodiment, a conference gooseneck microphone can provide noise cancellation. In a large conference hall, echoing can be a problem for sound recording. The echo recorded by the microphone can cause howling. A severe echo can prevent the user from turning up the speaker volume and causing limited audibility. Meeting rooms and meeting rooms decorate the wall with expensive sound absorbing materials to reduce echo to achieve higher speaker volume and provide a uniform sound field distribution throughout the audience. Electronic echo cancellation equipment can be used to reduce echo and increase speaker volume; however, this equipment is quite expensive, may be difficult to assemble, and often requires the use of acoustic experts.

In one embodiment, a dual microphone noise cancellation conference microphone can provide an inexpensive and easy to implement solution to the echo problem in a conference hall or conference room. The dual microphone system described above can be placed in a tabletop gooseneck microphone. Each microphone in the hose is a pressure gradient bidirectional, unidirectional, or super-directional microphone.

In a headset, the user would like to have noise to eliminate the near-talk microphone, but there is no need to have a speaker microphone in front of his or her mouth. The microphone in front of the user's mouth can be annoying. In addition, moisture from the user's mouth will also condense on the surface of the Electret Condenser Microphone (ECM) film, after long-term use. After that, it will degrade the sensitivity of the microphone.

In one embodiment, a short hose speaker earphone can solve this problem by shortening the speaker, moving the ECM away from the user's mouth, and using a rubber tube to extend the noise of the microphone to eliminate the sound of the microphone. Some questions. This extends the effective close range of the ECM. This will preserve the noise cancellation ECM feature for distant noise. In addition, the speaker hose is lined with a windshield foam. This solution further makes the binaural headset computer suitable for use in enterprise customer service centers, industrial use, and general mobile use. In embodiments where the same dual microphone is present in the hose enclosure, the individual rubber barrels of each microphone will also be identical.

In one embodiment, the short hose speaker binaural earphone can be a wired or wireless binaural earphone. The binaural headset includes the short microphone (for example, ECM) hose speaker. The hose speaker extends from the user's cheeks from the housing of the binaural earphone that is straight or curved at the user's cheek. For example, the hose speaker will extend along the length of the cheek to the side of the user's mouth. The hose speaker contains a single noise cancellation microphone on the inside.

The hose speaker will further include a dual microphone inside the hose. Dual microphones are more effective at eliminating non-static noise, human noise, music, and high frequency noise. Dual microphones are more suitable for mobile communications, voice recognition, or Bluetooth binaural headphones. Although the two microphones can be identical; however, those skilled in the art can also design hose speakers with different models of microphones.

In embodiments with dual microphones, two microphones enclosed in their individual rubber barrels are placed in series along the inside of the hose.

The hose has a cylindrical shape; however, other shapes (for example, rectangular prisms, etc.) may be employed. The short hose speaker will have two openings, one at the tip and the second at the back. The surface of the hose is covered by a pattern of holes or slits to allow sound to reach the microphone inside the hose speaker. In another embodiment, the short hose speaker has three openings, one at the tip, the other at the center, and the other at the back. The openings can be equally spaced apart; however, those skilled in the art will be able to design other separation distances.

The microphone in the hose speaker is a two-way noise canceling microphone with a pressure gradient microphone element. The microphone will be enclosed in a rubber tube that extends the sound 埠 of the front and back sides of the microphone with the sound tube. The microphone element is sealed inside the long tube in the hermetic rubber barrel.

A microphone with a rubber long tube is placed inside the hose along the inside of the hose. A sound at the tip of the hose will align with the speaker opening, and a click on the back of the hose will align with the speaker opening. The rubber tube will deflect away from the ends of the hoses to allow for spacing between the ends of the hoses and the rubber barrel. This spacing further allows for a breathing room and space for placing a suitable thickness of the windshield. However, the rubber tube and the inner wall of the hose are still airtight. A windshield foam (for example, a windshield sleeve above the rubber tube) fills the air duct and the open space between the sound raft and the hose/opening.

Referring to Figure 9, the glasses 952 of Figure 9 are identical to the glasses 802 of Figure 8; however, instead, the system uses three microphones instead of two. The glasses 952 of FIG. 9 have a first microphone 954 arranged in the middle of the glasses 952, and a second microphone 956 arranged in the glasses 952. The left side, and a third microphone 958 are arranged on the right side of the glasses 952. The three microphones can be utilized in the three microphone embodiment described above.

An exploded view 1000 of an exemplary embodiment of the rubber long cylinders 1002a-b shown in Figure 10A. The rubber long cylinders 1002a to b are divided into a rubber long cylinder first half 1002a and a rubber long cylinder second half 1002b. Each of the rubber long cylinders 1002a to b has an inner lining of the material of the windshield 1008; however, Fig. 10A shows the windshield only in the second half of the rubber long barrel 1002b. In the case of a pressure gradient microphone, the air duct and the open space between the sound cymbal and the interior of the enclosure are filled with a windshield foam material (eg, a windshield sleeve positioned above the rubber barrel).

Figure 12 is a block diagram 1200 of an exemplary embodiment of a noise cancellation circuit utilized in the present invention. Signals 1210 and 1212 from the two microphones are digitized and fed to the noise cancellation circuit 1201. The noise cancellation circuit 1201 can be a digital signal processing (DSP) unit (for example, a software, a hardware block, or a plurality of hardware blocks executed on a processor). In one embodiment, the noise cancellation circuit 1201 is a digital signal processing (DSP) chip, a system on a chip (SOC), a Bluetooth chip, an audio codec with a DSP chip, ... Wait. The noise cancellation circuit 1201 can be placed in a Bluetooth binaural earphone near the user's ear, placed in the same-line control case with the battery, or placed in the connector, ... Wait. The noise cancellation circuit 1201 can be powered by the battery or power source of the device to which the earphone is connected, such as the battery of the device, or power from a USB, micro-USB, or Lightening connector.

The noise cancellation circuit 1201 includes four functional blocks that are all electronically connected (wireless or hard-wound): a Beam-Forming (BF) module 1202, and a desired audio activity detection (Voice). The Activity Detection (VAD) module 1208, an Adaptive Noise Cancellation (ANC) module 1204, and a single signal noise reduction (NR) module 1206. The two signals 1210 and 1212 are fed to the BF module 1202, which generates a main signal 1230 and a reference signal 1232 to the ANC module 1204. The closer microphone signal 1210 is collected from a microphone that is closer to the user's mouth, while the farther microphone signal is collected from a microphone that is relatively far from the user's mouth. The BF module 1202 also generates a main signal 1220 and a reference signal 1222 to the desired VAD module 1208. In a specific embodiment, the main signal 1220 and the reference signal 1222 are different from the main signal 1230 and the reference signal 1232 generated by the ANC module 1204.

The ANC module 1204 processes the main signal 1230 and the reference signal 1232 to cancel the noise in the two signals and output a noise-cancelled signal 1242 to the single-channel NR module 1206. The single signal NR module 1206 will post-process the noise canceling signal 1242 from the ANC module 1204 to remove any further residual noise. At the same time, the VAD module 1208 infers a desired Desired Voice Activity Detection (DVAD) signal 1240 from the main signal 1220 and the reference signal 1222, which indicates that there is voice in the main signal 1220 and the reference signal 1222 or There is no voice present. The DVAD signal 1240 is then used to control the ANC module 1204 and the NR module 1206 in accordance with the results of the BF module 1202. DVAD signal 1240 The ANC module 1204 and the single channel NR module 1206 are shown to indicate which part of the signal has audio data to be analyzed, which can improve the ANC module 1204 and the single channel NR mode by ignoring the portion of the signal that has no audio data. The processing efficiency of group 1206. The desired voice signal 1244 will be generated by the single channel NR module 1206.

In one embodiment, the BF module 1202, the ANC module 1204, the single NR reduction module 1206, and the desired VAD module 1208 utilize linear processing (eg, a linear filter). A linear system (which uses linear processing) will satisfy the superposition characteristics as well as the scaling characteristics or homogeneity. The meaning of the superposition feature is that the output and input of the system are proportional. For example, if the following relationship is satisfied, the function F(x) is a linear system: F(x ₁ +x ₂ +...)=F(x ₁ )+F(x ₂ )+...

If the output and the input are proportional to the scaling, then the one-degree scaling characteristic or homogeneity is satisfied. For example, if the following relationship is satisfied, the function F(x) satisfies the scaling property or homogeneity, where α is a scalar quantity: F(αx)=αF(x)

Conversely, nonlinear systems do not satisfy the first two conditions.

Previous noise cancellation systems used nonlinear processing. By using linear processing, increasing the input will change the output proportionally. However, in nonlinear processing, increasing the input will change the output in an unbiased manner. The use of linear processing provides the advantage of speech recognition due to improved feature extraction. The speaker recognition algorithm was developed based on noise-free audio that was recorded without distortion in a quiet environment. The linear noise cancellation algorithm does not introduce nonlinear distortion into the noise-cancelled speech. Speech recognition can cope with linear distortion in speech, but it cannot cope with the nonlinear distortion of speech. The linear noise cancellation algorithm is "transparent" to the speech recognition engine. In the non-line Training speech recognition is an impossible behavior in the variation of sexual distortion noise. Nonlinear distortion interrupts the feature extraction required for speech recognition.

An example of a linear system is the Weiner filter, which is a linear single channel noise removal filter. A Weiner filter is a filter for generating a desired or target random processed prediction value by linearly time-varying filtering of the observed noise processing, assuming a known static signal , noise spectrum, and additive noise. The Weiner filter minimizes the mean square error between the predicted random process and the desired process.

The far microphone signal 1312 is input to a frequency response matched filter 1304. The frequency response matched filter 1304 adjusts the gain, phase, and shape of the frequency response of the far microphone signal 1312. For example, the frequency response matching filter 1304 can adjust the signal for the distance between the two microphones, so that an output reference signal 1332 representing the far microphone signal 1312 can be combined with the representative microphone. The main signal 1330 of the signal 1310 is processed. The main signal 1330 and the reference signal 1332 are sent to the ANC module.

The closer microphone signal 1310 is output to the ANC module as the main signal 1330. The nearer microphone signal 1310 is also input to a low pass filter 1306. The reference signal 1332 is input to a low pass filter 1308 for creating a reference signal 1322 that is sent to the desired VAD module. In one embodiment, for example, the low pass filters 1306 and 1308 adjust the signal in the "close-range speech situation", for example, from 2 kHz to 4 kHz. Decrease the roll off frequency (low off). However, other frequencies can be used in different designs and at different distances between the microphone and the user's mouth.

The short-term power modules 1404 and 1406 may include a square root mean square (RMS) detector, a power (PWR) detector, or an energy detector. The short time power modules 1404 and 1406 output signals to the respective amplifiers 1408 and 1410. The amplifiers can be logarithmic converters (or logarithmic amplifiers). The logarithmic converters 1408 and 1410 are output to a combiner 1412. The combiner 1412 is configured to combine a plurality of signals, for example, combining one of the main signal and the at least one reference signal for detecting the reference signal by using the detected value of the main signal The measured value (or vice versa) is used to generate an audio active difference signal. The audio activity difference signal is input to a single channel VAD module 1414. The single channel VAD module can be a conventional VAD module. The single channel VAD module 1414 outputs the desired audio activity signal.
